Doggone it, I can't help but recall someone awhile back on RR writing about "I got a drawer full of antennas throughout the years...". I think I am joining the club now.
I just bought another REM-820S for my BCD436HP...guess I'll be picking up some REM-842S, too!
It's interesting that I have some rubber duck antennas that are 40 to 45 years old and in great shape and others no more than 20 years old that just crumbled to dust
Nice antenna but compared to my diamond rh77ca it's not quite as good but close
Something related, I guess, since the topic is Remtronix antennas for the SDS100. I just got a new SDS100, but for some reason, my old Remtronix REM-810S will not thread on all of the way. I don't want to force it. It was working fine on my BCD436, so I'm not sure what's wrong all of a sudden. I was wondering if anyone knows what the thread configuration is. I might be able to borrow a thread tap/die to chase the threads and see if that is the problem before I buy a new antenna.

Absolutely don't do that. The collar around the SMA connector means the exposed portion is about 2.5mm shorter than the connector on the 436, and most SMA antennas don't thread on far enough for the center pin to connect. Chasing the threads will just loosen the connector even more.I might be able to borrow a thread tap/die to chase the threads and see if that is the problem before I buy a new antenna.
A drawer full of antennas. That would be me, too. But I recommissioned a roll-up gun cleaning kit with lots of pockets and that has become the new home for my rubber duckies. Works well and saves space
I see that is actually the case after looking at it about 20 more times and finally breaking down and accepting that a new antenna, likely the Remtronix 820S is the best way (for what I am listening to most of the time).Don't do that. It has nothing to do with the threads, and everything to do with the plastic collar around the outside of the SMA connector. A regular SMA antenna will not mate correctly.
Garys,I took the SDS100 and both antennas out for a ride. I found a good location where I should be able to get wide area reception based on past experience.
What I found was that on 900Mhz the 842B is slightly superior to the 820B, on 800Mhz they are more or less equal. On 700Mhz the 842B is not as good as the 820B, but it's not as deaf as it appeared in my house. In fact sitting in the driveway in my truck, the 842B picked up the 700Mhz system that it wouldn't pick up in the house at all.
On UHF/UHF T, the 842B is very good. It's noticeably better than the 820B which isn't bad on that band at all.
On VHF, the 842B is much better than the 820B. I locked on to my "Private Ambulance" system which has to different agencies that operate VHF repeaters. Sitting on the seat of my truck, the 842B picked up both systems primary repeaters pretty well. I expect if I had the radio up on the dash, it would be better.
Since the SDS scanners process digital audio better, I think my next test will be using a BNC Right Angle adapter and plugging the 842B in to see how it well it works on the 536HP.
Any updates on how this antenna works? I've ordered one and am an anxiously awaiting it.
